1. A valve comprising:
a housing; and
a valve body having a fluid inlet and a fluid outlet, wherein the fluid inlet and the fluid outlet are coaxial, the valve body comprising a first valve element and a second valve element arranged in said housing, wherein:
the first valve element is conformed as a sleeve with an inner surface that tapers at least in sections toward the fluid outlet and the second valve element is conformed as a cone mounted to the inner surface of the sleeve with the same incline as the inner surface of the sleeve so as to form a gap between the first valve element and the second valve element, said cone having a central, axially extending channel open to the fluid inlet,
an annular space open to the fluid outlet is formed between the sleeve and an inner surface of the housing,
the sleeve has through holes towards the annular space and the cone has through openings towards the fluid inlet,
the sleeve and the cone are axially adjustable relative to one another,
the fluid outlet is provided concentrically and separately from the central, axially extending channel in the cone, and
the fluid outlet is included in a cylindrical end region of the cone.
